Ida, Ark. bettered the all-time high school indoor pole vault record for a second time this month, clearing 17 feet, 9 inches on June 14 in an open meet at the Arkansas Vault Club Training Center in Black Springs, Ark. A subsequent 18-0 clearance was ruled a foul when Irwin steadied the bar with his left hand.

Dathan Ritzenhein looks to continue breaking barriers and personal bests Sunday in the World Half Marathon Championships in Birmingham, England.
